Anatomy: Home anti-theft technology and alarm system construction

　　Home anti-theft technology

　　At present, the anti-theft means of ordinary families are mainly human and physical defense (such as anti-theft doors, iron guardrails, etc.). It is recommended to adopt technical prevention means to achieve a safer and smarter effect. It is generally recommended to install infrared anti-theft alarm devices, electromagnetic password door locks, and electronic network alarm systems.

　　Infrared anti-theft alarm device: When this alarm device is in working condition, it can emit infrared light that is invisible to the naked eye. As long as a person enters the light control range, the device will immediately sound an alarm. If a thief enters, the residents can immediately discover it, but the thief himself is unaware and often surrenders.

　　Electromagnetic password door lock: When installing this type of lock, you need to enter the password first when unlocking from the outside, otherwise the lock cannot be unlocked; if it is pried open, the alarm device on the lock will sound an alarm. This will alert the people in the room or neighbors, which can scare away the thief or capture the thief.

　　Actively cooperate and participate in the urban community alarm networking system. After the user installs this alarm device, in case of dangerous situations (such as burglary), the alarm will automatically sound the alarm through the pre-set defense zone, and the police station's alarm receiving device will immediately and automatically display the user's exact address, so the police can quickly arrive at the scene of the crime and arrest the criminal.

　　Home burglar alarm system set up

　　Burglar alarms have recently become popular among families and have become the first choice for many families to purchase security equipment. The continuous advancement of technology has also enabled burglar alarms to develop from a single anti-theft function in the past to a comprehensive function that can not only prevent theft but also alarm for gas poisoning, fire, home first aid, etc. Now, let's learn about home burglar alarm systems:

　　1. The core of anti-theft alarm equipment: anti-theft alarm host

　　The anti-theft alarm host consists of three parts: detector (also known as alarm), transmission channel and alarm controller. The device composed of electronic and mechanical parts used to detect intruders' intrusion behavior is the key to the anti-theft alarm host, and the sensor is the core component of the alarm detector. Using sensors based on different principles, alarm detection devices of different types, different uses and different detection purposes can be constructed to judge and receive alarm signals from various detectors. After receiving the alarm signal, the alarm can be alarmed according to the pre-set alarm method. For example, the sound and light alarm is activated, and multiple alarm telephones that have been set are automatically dialed. If it is connected to the community alarm center, the signal can be transmitted to the community alarm center. The alarm host is equipped with a remote control, which can control the host remotely.

　　2. Contact of anti-theft alarm equipment: infrared anti-theft detector

　　It adopts microcomputer digital signal technology, high stability detection device, and innovative design. It has temperature compensation, strong white light resistance, electromagnetic interference resistance, and eliminates various false alarm factors. When an intruder passes through the infrared detector, the infrared detector sends a signal to the alarm host, and the alarm host immediately alarms.

　　3. One of the "minions" of anti-theft alarm equipment: door magnetic and window magnetic detectors

　　After the alarm host is armed, if an intruder opens the doors and windows equipped with door magnets and window magnets, the door magnets and window magnets will send a signal to the alarm host, and the alarm host will immediately activate the alarm.

　　4. The second "claw" of the anti-theft alarm equipment: smoke detector

　　Smoke detectors are also called smoke fire detectors, smoke detectors, smoke detectors, smoke probes and smoke sensors. They are mainly used in fire protection systems and are also used in security system construction. Smoke fire detectors use photoelectric sensors with special structural designs and are produced using SMD patch processing technology. They have the characteristics of high sensitivity, stability and reliability, low power consumption, beautiful and durable, and easy to use. The circuit and power supply can be self-checked, and simulated alarm tests can be performed.

　　Using an advanced radioactive source and contrast space, open space to detect heavy ions, it is sensitive to open flames, no fire, smoke, or smokeless combustion. When harmful gases are detected, the indicator light turns red and sends an alarm signal to the host.

　　5. The third "claw" of anti-theft alarm equipment: harmful gas detector

　　The gas detector consists of a transmitter with a gas sensor, which can detect gas. Detection range: detection of combustible gases such as methane, ethane, and liquefied petroleum gas Detection concentration: methane, propane, and ethane are greater than 10,000 PPM, alcohol and acetate are greater than 1,000 PPM, and ethylene and ammonia are greater than 500 PPM Working environment temperature: -10℃～5℃ Humidity: less than 95%

　　6. Operator of anti-theft alarm equipment: remote control

　　It is used to arm and disarm the anti-theft alarm system. Its usage is the same as that of common car anti-theft remote controls.

　　The home anti-theft alarm system is the most important and final link in the entire residential security system. When a thief illegally breaks into a resident's home or an emergency occurs, such as a gas leak, fire, or an elderly person's acute illness, the various electronic detectors installed indoors will automatically alarm, and the alarm center will receive the alarm information within tens of seconds, and quickly dispatch security or ambulance personnel to the resident's site to handle the situation.
